This is just about as perfect as comedy crossovers get. Go read, even if you don’t know Blackadder. The Tenth Doctor has to enlist the help of one Edmund Blackadder to stop a marriage. Much sarcasm and hilarity ensues.

Just for an example, and in order to show how completely random this random fic category will be, if I feel so moved. And, moreover, because this made me laugh so much last night, I need to share it with the world:

We all know what the pass is like at this time of the year, so the fellowship decide to travel by plane to Gondor. Going by the security issues this provokes, they probably should have taken Aragorn’s advice and gone by train… I defy someone to read this and not at least smile. Plus, Primsong is one of my favourite fanfic authors, but hasn’t done many crossovers (yet), so I want to sneak a rec in here somehow.

A thoroughly entertaining cross with a twist. Let’s just say that the Doctor’s not popular with the other members of this support group. Plus points, of course, for Rimmer meeting another version of himself (one we’ve encountered previously, but he hasn’t).

Rimmer finally gets to meet an alien and Lister gets to meet another human (albeit one who likes blowing things up a lot). Excellent, fully in keeping with both shows and very funny.

I’ve only just now found this and it’s lovely. I think it might even be my favourite. The Doctor’s thrown 3 million light years off course, messing up Lister’s poker night. Which means that Rimmer gets to meet an alien and Holly needs repairing with washing-up liquid. (And I love any good use of Holly.)

This one’s a lovely, short, summery tale of the Fifth Doctor meeting Bertie Wooster and Jeeves. Before you know it, there’s complications and a situation that requires Bertie to purloin an artefact from his Aunt Dahlia.

A bit of an oddity among crossovers, in that the Doctor seems to have regenerated into Wooster. But he still needs Jeeves to sort out the intergalactic crises and the fact it’s by this author should be all that’s needed to recommend it.

While having been determined not to do the foolhardy thing of attempting a Wodehouse crossover, I gave in. The Tenth Doctor is searching for an alien artefact while posing as Lord Emsworth’s latest secretary and causing trouble, as all secretaries do.
